Sri Lankan President Maithripala Sirisena confirmed the death of Mouvli Zahran Hashim, on April 26. Hashim was also known as Mohammed Zahren.
The bombings took place at churches and hotels in and around the country’s capital on April 21. At least 250 people died, with hundreds of others injured.
“What intelligence agencies have told me is that Zahran was killed during the Shangri-La attack,” Sirisena told reporters, according to AFP. The Shangri-La Hotel is in Colombo.
He said that Hashim was accompanied by a second bomber, Ilham Ibrahim, in the attack against the hotel.
He said the death of Hashim was confirmed in part by surveillance footage from the scene.
Before the death was confirmed, intelligence agencies were hunting for Hashim, the leader of the Islamic terror group National Thowfeek Jamaath (NTJ).
Authorities said that NTJ was behind the bombings, with help from an international network.
A video released by the ISIS propaganda agency Amaq showed a man appearing to be Hashim with seven masked persons pledging allegiance to the Middle East-based terror group that seeks to impose Shariah on territories they conquer by force.
“We pledge allegiance … and to obey him on everything either in easy or difficult conditions,” the group said, before praising Allah, the word Muslims use for God.
Hashim has for years posted videos on YouTube outlining his extremist views, including calling for all non-Muslims to be eliminated and praising ISIS. He routinely threatened Christians, Buddhists, and Hindus.
In one of the clips posted to Facebook, Hashim threatens to attack civilians with explosive-laden vehicles, reported Reuters.
“Before the strength of a mujahideen (holy warrior), your army, police, and intelligence are all doomed to fail,” Zahran said in the clip.
The brother of Ibrahim, who accompanied Zahran to the hotel, was also involved in the bombings and was identified as Inshaf Ibrahim.
